ABSTRACT:
An integrated digital calibration circuit and digital to analog converter includes a digital to analog converter (DAC) and a digital calibration circuit including a memory for storing predetermined end point coefficients of the digital to analog converter transfer function; and an arithmetic logic unit for applying the end point coefficients to the DAC input signal to adjust the end points of the DAC and/or analog signal chain.
